Help: how to upgrade urllib3 for solve "filedescriptor out of range in select()" issue

[abc100m]

requests version: 2.12.4
python version: 2.7.9
platform: linux(CentOS)

issue occured:

ValueError: filedescriptor out of range in select()

detail description : urllib3/urllib3@a49bec5

and this issue have been fixed :
urllib3/urllib3#589
sigmavirus24/urllib3@eb8264f

I wonder why requests don't upgrade urllib3? and how can I upgrade urllib3 for requests?

Requests uses a vendored copy of urllib3, so we ship our own updates to it. That means you cannot upgrade urllib3 separately to requests.

While I am here, I should note that there is no released version of urllib3 that contains that fix, you'd have to use urllib3 from master. If that's the case, you are best served by cloning the Requests repository and updating the copy of urllib3 inside it and installing that.

@Lukasa Sorry to bother on closed issue but I'm wondering why should this fix not being updated in Request?

[Lukasa]

@RobGThai We pushed requests v2.13 today which contains that fix.
